I remapped the right most knob on each side to a super filter then slided the fx paramaters 1 and 2 to the left 2 knobs and switched the fx select from a knob to a button (cycle through). This is the leftmost red button on the above picture.
The remaining three loop buttons are set to [ 1/2 ] [Loop ] [ 2x ]
If we had a section on the site (or could send them to Phil) I would share the mapping, but it’s easy enough to do.
Keep in mind, my guess is you are using traktor so there may be better mappings following hessler’s link. I have a regular mixtrack that came with VDJ LE so I am using DJAY4 by algoriddim instead.
